W ater quality is measured by several factors, such as the concentration of dissolved oxygen, bacteria levels, the amount of salt or salinity , or the amount of material suspended in the water turbidity. In some bodies of water, the concentration of microscopic algae and quantities of pesticides, herbicides, heavy metals, and other contaminants may also be measured to determine water quality. Poor water quality can pose a health risk for people.
At APEC, we strive to provide the best drinking water available to everyone. Even if it means offering a free system to those in need. Water quality is defined in terms of the chemical, physical, and biological content of water. The water quality of rivers and lakes changes with the seasons and geographic areas, even when there is no pollution present. There is no single measure that constitutes good water quality.

This major reference work provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply.
Every system is designed to meet the needs of specific applications, providing high levels of water quality, consistency and reliability using a wide range of advanced technologies. We also offer full technical support, training and aftermarket services, to ensure a maximum return on investment and unrivalled value for our customers. The Labwater units incorporate an easily replaceable cartridge, containing specifically designed resin, which changes colour through absorption of ionic contaminants, facilitating a low level of maintenance. On complete colour change from blue to brown, replace the cartridge. The units are typically wall mounted and are easily connected via a dedicated hose supplied separately to a tap or stopcock and operate direct from water pressure thus requiring no external electrical supply
of the quality of the water resources. Types of Processes and factors of water purification are. categorized by Physical, Chemical and Biological.
Water is of fundamental importance for life on earth. The synthesis and structure of cell constituents and transport of nutrients into the cells as well as body metabolism depend on water. The probable contaminations and their possible routes are discussed in the present review.
